Ethel's sweetheart makes her a present of a large bottle of perfume. Bill and Izzy hit upon the brilliant scheme of filling empty bottles and selling them for spring water. But when they turn the faucet they discover that the odor is not precisely what might be expected from nature's crystal wells, so they steal Ethel's perfume and doctor their bum goods. It chances that another office holder, who has bought water from Bill and Izzy spills some on his coat. His wife notices the odor, and becoming suspicious, she traces it to Ethel. Ethel does a little detective work, and the two office boys are caught in the act. But his latest venture costs Bill his job.
